Inside, he found his own NASA backpack stuffed with goodies- a puzzle with a picture of Earth, a packet of experiments and activities for kids about space and flight, some pencils, lapel pins, stickers, a poster for his room, 3D viewers with pictures of space, and temporary tattoos of all the planets.

He was thrilled.

He put the Neptune tattoo on immediately and was still wearing it a week later (despite having had a bath...he managed to preserve it somehow).

The best part, though, was a letter addressed to him on NASA letterhead, commending him for his interest in all things space-related. It encouraged him to keep studying science and concluded with "maybe we'll see you out there as an astronaut someday."

He hugged the letter and said seriously, "NASA has their eye on me. I need to be on my best behavior since I'm training to be an astronaut."
